Byssinosis [n 1] is an occupational lung disease caused by inhalation of cotton or jute dust in inadequately ventilated working environments and can develop over time with repeated exposure. [ 2 ] [ 3 ] Byssinosis commonly occurs in textile workers who are employed in yarn and fabric manufacture industries.
Similar to hypertensive retinopathy, evidence of nerve fiber infarcts due to ischemia (cotton-wool spots) can be seen on physical exam. Symptoms may include headache, nausea, or vomiting. Chest pain may occur due to increased workload on the heart resulting in inadequate delivery of oxygen to meet the heart muscle's metabolic needs.
The presence of cotton wool spots may resolve independently over time, typically in 4–12 weeks, or may depend on the underlying disease causing the condition. [3] [4] Diagnosis and treatment of the underlying disease state may be beneficial in the treatment and management of cotton wool spots. [3]
21% of Americans have chronic pain. A new study found that diets rich in vegetables, fruits, grains, lean proteins, and dairy was linked to less chronic pain.
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia.
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Determining if there are radicular symptoms, such as pain, numbness or weakness that radiate down limbs, is important for differentiating between central and peripheral causes of back pain. The straight leg test is a maneuver used to determine the presence of lumbosacral radiculopathy , which occurs when there is irritation in the nerve root ...
Symptoms of acute limb ischemia can occur anywhere from minutes to days. [2] The classic symptoms of acute limb ischaemia include: Pain - Usually starts distally in the extremity and will move proximally and increase in severity as ischemia worsens; Pallor - The limb may appear pale and mottled
